Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a rigid gas pipe ignitor is used, then the ignitor structure is simple and easy to manufacture, but the directional movement and control of the nozzle tip is limited
Solution Approach 1:
The patent applies the dynamics principle by replacing the rigid ignitor structure with a flexible hose assembly that can dynamically adapt to the movement and tilting of the nozzle tip. The flexible hose allows the ignitor to move with the nozzle while maintaining the gas supply connection, thereby resolving the contradiction between structural simplicity and directional movement control.
Solution Approach 2:
The patent directly applies the flexible shells principle by using a flexible hose to replace the rigid gas pipe. This flexible hose can bend and flex to accommodate the tilting and movement of the nozzle tip, providing both the simplicity of a hose structure and the adaptability needed for directional control.
2Ease of operation
If slots are inserted into directional blades to allow nozzle tip tilting, then the nozzle tip can move upward and downward, but the effectiveness of nozzle tips is reduced
Solution Approach 1:
The patent applies the taking out principle by removing the slots from the directional blades, thereby eliminating the modification that reduced nozzle effectiveness. Instead, the flexibility is achieved through the flexible hose assembly that connects the ignitor to the nozzle, allowing tilting without compromising the integrity or effectiveness of the nozzle blades.
3Adaptability or versatility
If a rigid gas pipe ignitor is coupled to a movable nozzle tip, then the ignitor can be mounted on moveable structural elements, but the operational integrity and movement of structural elements is compromised
Solution Approach 1:
The patent applies the flexible shells principle by using a flexible hose assembly that can accommodate the movement and operational changes of the movable structural elements. This flexible connection maintains the gas supply while allowing the structural elements to move and tilt without compromising operational integrity.
Solution Approach 2:
The patent applies dynamics by using a flexible, adaptable connection that can respond to the movement of the structural elements. The flexible hose dynamically adjusts to the changing positions and orientations of the movable components, maintaining system reliability throughout the range of motion.

AI summary
A gas pipe ignitor for igniting a non-premixed air and fuel mixture includes a housing having an axially interior space along its length, a supply end segment, a flame end segment axially spaced from the supply end segment, and a flexible segment spaced between the supply end segment and the flame end segment. A fuel supply conduit extends axially within the housing, and the fuel supply conduit is operatively flexible with the flexible segment. An ignition conduit extends axially within the housing, and the ignition conduit is operatively flexible with the flexible segment. A detector conduit extends axially within the housing, and the detector conduit is operatively flexible with the flexible segment. An air supply conduit is operatively connected to the housing at the supply end segment and provides combustion air within the interior space.
